[Q]: I know that the answer to the question "what is a negative effect of hydrogen on storage tanks as stated in the text" is in "Hydrogen is highly soluble in many rare earth and transition metals and is soluble in both nanocrystalline and amorphous metals. Hydrogen solubility in metals is influenced by local distortions or impurities in the crystal lattice. These properties may be useful when hydrogen is purified by passage through hot palladium disks, but the gas's high solubility is a metallurgical problem, contributing to the embrittlement of many metals, complicating the design of pipelines and storage tanks.". Can you tell me what it is?

[A]: embrittlement


input: Please answer the following: I know that the answer to the question "What was the First Council of Nicaea considered?" is in "At the time, there were many varying opinions about Christian doctrine, and no centralized way of enforcing orthodoxy. Constantine called all the Christian bishops throughout the Roman Empire to a meeting, and some 318 bishops (very few from the Western Empire) attended the First Council of Nicaea. The purpose of this meeting was to define Christian orthodoxy and clearly differentiate it from Christian heresies. The meeting reached consensus on the Nicene Creed and other statements. Later, Philostorgius criticized Christians who offered sacrifice at statues of the divus Constantine. Constantine nevertheless took great pains to assuage traditionalist and Christian anxieties.".

Please answer this: I know that the answer to the question "What was a positive of the second system?" is in "The Xbox 360 sold much better than its predecessor, and although not the best-selling console of the seventh-generation, it is regarded as a success since it strengthened Microsoft as a major force in the console market at the expense of well-established rivals. The inexpensive Nintendo Wii did sell the most console units but eventually saw a collapse of third-party software support in its later years, and it has been viewed by some as a fad since the succeeding Wii U had a poor debut in 2012. The PlayStation 3 struggled for a time due to being too expensive and initially lacking quality titles, making it far less dominant than its predecessor, the PlayStation 2, and it took until late in the PlayStation 3's lifespan for its sales and game titles to reach parity with the Xbox 360. TechRadar proclaimed that "Xbox 360 passes the baton as the king of the hill – a position that puts all the more pressure on its successor, Xbox One".". Can you tell me what it is?

Answer: inexpensive


Problem: I know that the answer to the question "What was the bottom cutoff for introduced drugs that were required by law to be effective?" is in "The thalidomide tragedy resurrected Kefauver's bill to enhance drug regulation that had stalled in Congress, and the Kefauver-Harris Amendment became law on 10 October 1962. Manufacturers henceforth had to prove to FDA that their drugs were effective as well as safe before they could go on the US market. The FDA received authority to regulate advertising of prescription drugs and to establish good manufacturing practices. The law required that all drugs introduced between 1938 and 1962 had to be effective. An FDA - National Academy of Sciences collaborative study showed that nearly 40 percent of these products were not effective. A similarly comprehensive study of over-the-counter products began ten years later.". Can you tell me what it is?

A: 1938


Problem: Given the question: I know that the answer to the question "What was a position of rpestige?" is in "The Qing organization of provinces was based on the fifteen administrative units set up by the Ming dynasty, later made into eighteen provinces by splitting for example, Huguang into Hubei and Hunan provinces. The provincial bureaucracy continued the Yuan and Ming practice of three parallel lines, civil, military, and censorate, or surveillance. Each province was administered by a governor (巡撫, xunfu) and a provincial military commander (提督, tidu). Below the province were prefectures (府, fu) operating under a prefect (知府, zhīfǔ), followed by subprefectures under a subprefect. The lowest unit was the county, overseen by a county magistrate. The eighteen provinces are also known as "China proper". The position of viceroy or governor-general (總督, zongdu) was the highest rank in the provincial administration. There were eight regional viceroys in China proper, each usually took charge of two or three provinces. The Viceroy of Zhili, who was responsible for the area surrounding the capital Beijing, is usually considered as the most honorable and powerful viceroy among the eight.". Can you tell me what it is?
